It's our annual "Best of 2014" episode, so Khail and Ashley took some time to reminisce about all the really cool, weird, interesting, awe-inspiring and fun things that happened this year. Not only are we talking about our favorite things, we're reading yours, too!

We're all for a fleet of robotic security guards, but we're not so sure about giving them weapons (like tasers) to deploy on people. When someone gets tasered for accidentally littering, that's gonna be a real problem. How do you reason with a robot guard?
